Paediatric doctors error rate in detection of paediatric elbow injuries in Rahima Moosa mother and child hospital
Introduction: Elbow fractures are common paediatric injuries that are often misdiagnosed. Quality imaging and accurate interpretation is essential to avoid complications that can result in growth disturbance. Aim: The aim of this study was to determine error rates of elbow injuries by medical doctors in paediatric department in Rahima Moosa Mother and Child Hospital. Methods: 28 doctors participated in the study. 20 preselected radiographs (10 normal and 10 abnormal) were projected in a power point slide show. The doctors completed a tick sheet to assess whether the x-ray was normal or not. This was followed by a 20 minute tutorial on the approach to paediatric elbow x-rays. Following that, the same images were projected in a different sequence and with a more detailed tick sheet for the readers to evaluate. Results: The detection rate of elbow fractures by paediatric doctors was poor. Although there was an improvement in the detection of fractures before (52.1%) and after (56.4%) the tutorial, the difference was not statistically significant (paired t-test; p=0.16). Conclusion: The paediatric elbow is a common site where pathology is missed on x-rays. The study showed that the detection rate of elbow fractures by the paediatric doctors is poor, even after a tutorial on the radiological features. We recommend on-going inservice training of clinicians to improve detection of fractures.
